In [Co(en)3]+3 S.F.L. is present and hence highest value of CFSE
In rest all complexes WFL is present hence CFSE will be low.
[Co(en)3]+3⇒Co+3 and en (SFL)
Co+3⇒[Ar]3 d6

First and second ionization enthalpies of lithium are $520$ kJ mol$^{-1}$ and $7297$ kJ mol$^{-1}$ respectively. Energy required to convert $3.5$ mg lithium (g) into $\text{Li}^{2+}$(g) $[\text{Li(g)} \rightarrow \text{Li}^{2+}\text{(g)}]$ is _______ kJ mol$^{-1}$. (nearest integer) [Molar mass of Li $= 7$ g mol$^{-1}$]
